I loved it! This was a really enjoyable movie ... warm and fun, lots of good characters, great dancing and music, etc. It touched on a serious subject (segregation), but managed to do it without feeling heavy, preachy or angry.
Amazing performances by everyone .. especially John Travolta! Little Inez was adorable .. and a great dancer. I loved Queen Latifah ... she was amazing.
The second half of the movie feels much "stronger" and better than the first. I thought this movie definitely got better as it went along, in terms of story, acting, singing, and dancing (basically, everything).
